When type B agglutinogen is not present on the surface of RBC of a person, his plasma would contain ____ agglutinins.
1. Anti-a 2. Anti-b
3. Both anti-a and anti-b 4. None
A person with AB blood group:
| 1. | Has A and B antigens in his plasma |
| 2. | Has antibodies on RBC surface |
| 3. | Can receive blood transfusion from a person of his own group. |
| 4. | Can donate blood to all other group recipients |
Person with blood group AB is considered as universal recipient because he has
| 1. | Both A and B antigens on RBC but no antibodies in the plasma |
| 2. | Both A and B antibodies in the plasma |
| 3. | No antigen on RBC and antibody in the plasma |
| 4. | Both A and B antigens in the plasma but no antibodies. |
A person with unknown blood group under ABO system, has suffered much blood loss in an accident and needs immediate blood transfusion. His one friend who has a valid cetificate of his own blood type, offers for blood donation without delay. What would have been the type of blood group of the donor friend?
| 1. | Type AB | 2. | Type O |
| 3. | Type A | 4. | Type B |
The universal donor and acceptor will be–
| 1. | O– and AB– | 2. | O– and AB+ |
| 3. | O+ and AB– | 4. | O+ and AB+ |
ABO blood grouping is based on
| 1. | presence of two soluble antibodies |
| 2. | absence of two surface antigens |
| 3. | presence of two surface antigens |
| 4. | both (2) and (3) |
If a person is AB – , who cannot donate blood to this person?
| 1. | any person with Rh antigen | 2. | any person with O+ only |
| 3. | any person with AB– | 4. | all people except A+ |
A person with blood group O– can take blood from
| 1. | O+ person | 2. | O– person |
| 3. | A+ person | 4. | both (1) and (2) |
When the plasma of a person has both anti A and anti B antibodies the blood group of this person would be:
1. A
2. B
3. AB
4. O
The most popularly known blood grouping is the ABO grouping. It is named ABO and not ABC, because 'O' in it refers to having:
| 1. | other antigens besides A and B on RBCs |
| 2. | over dominance of this type on the genes for A and B types |
| 3. | one antibody only- either anti A or anti-B on the RBCs |
| 4. | no antigens A and B on RBCs |
